Title: Launcher pushing a car with bucket
Lab goal/question:
Determine at what distance away from the table and at what angle of launch will the cart move and to observe the horizontal and vertical changes as collision takes place in the paper Dixie cup.
Materials: dixie cup, projectile launcher, marble, bricks, white tub,meter stick, car and tape.
Procedure:
1. Determine inital velocity of the marble
2. Determine angle of launch at 2 clicks
3. Through the use of trial and error, determine the distance away from the table that the launch needs to occur in order for the marble to reach its higest point when it reaches the table
4. Find distance away from table
Data/calculations:
Vy=sin(x)
Vf=0
Vi=3.83 m/s
sin(x)=52.93 degrees
actual= 42-45 degrees
Vx=about .94 meters
length of launcher= 16 cm
Reflection/Conclusion:
In our first trial, we figured out the angle of launch should be about 80 degrees. The problem with this is that 80 degrees is almost a vertical launch, which means high vertical velocity and low horizontal velocity. This will result in the ball hitting the cup with very little velocity in which the car would move very little. Through the manipulation of the distance away from the table that the launch will take place and the height of the starting launch, we were able to determine that the best possibility to push the car the farthest would be a perfectly horizontal launch. This is because a perfectly horizontal launch gives the marble a maxium horizontal velocity because there is no vertical component to the launch. To reflect back on to this experiment, we could have taken measurement more carefully because our original angle of launch was way of of the actual angle of launch. Through the use of trial and error, we were able to find the true angle of launch.Also, we could of done more trials to get more accurate data.
